The Incredible Naked Bouncing Egg

WE LOVE SCIENCE!! And seriously, who doesn't?! I remember being young and when my neighbors, my brother and I would find ourselves with nothing to do, we would scour the kitchen cabinets looking for things to dump in a bowl and called it a potion. It usually ended with the girls daring the boys to taste test whatever we had concocted, which ultimately led to a "burial" in which said concoction was poured in a hold we had dug in the back yard. Well, these days it's really no different with my own kids :) Busy and the Beans will make potions and experiment using anything they can find in the kitchen!! Which leads us to yesterday. They asked if they could hard boil an egg to see if it bounced. Great idea, right?! So in the name of science, we tried it.

As it turns out, hard boiled eggs don't bounce all that well ;)

But like many times before, this gave me another idea to explore. I remembered seeing another egg experiment all over Pinterest about dissolving the shell off an egg using vinegar. So to keep in the theme of eggs, we decided to give it a try :)

What You Need:

An egg

Vinegar

A cup or bowl deep enough to cover the egg completely

What To Do:

Put the egg in the cup and pour enough vinegar in the cup to cover the egg completely.

Wait. *You need to wait about 48 hours for the shell to dissolve completely.

Once the shell has dissolved, since off the goop and start bouncing! *Not too high of a drop! It could pop!

For this experiment, like most science experiments we do, I had Busy write their predictions about what would happen to the egg in their science journal. Beans thought it might explode and Busy predicted that it would get soft. After the experiment was complete, we discussed their original predictions and although Busy was right, she did say that she was not expecting the shell to come off. She thought the shell would just get softer. Then after a couple of days of coming back again and again to play with the soft naked egg, the Beans asked if he could pop it. So armed with a toothpick, he jabbed his way through the membrane to expose the yolk! All in the name of science ;)
